Description

Multipurpose Medical Instrument Internal Structure Sterilizer

technical field

The invention relates to a sterilizer, in particular to a machine for sterilizing the internal structures of various medical instruments.

Background technique

At present, in order to enable the contaminated instrument to be used again, most of the disinfection methods either replace disposable items or use disinfectant to wipe and soak the instrument or directly irradiate the instrument with ultraviolet rays. There are certain limitations in both methods, such as the replacement of disposable items will increase the cost of disinfection, especially some devices cannot be replaced. Wiping and soaking the instrument with liquid disinfectant can damage the surface coating of the internal parts of the medical instrument and accelerate the aging speed. At the same time, wiping with disinfectant may also cause cross-infection of diseases and spread of infectious diseases. The use of ultraviolet rays is ineffective for disinfection of the interior of the instrument. Chinese patent 200420029406.4 discloses a humidifier and a multi-purpose medical instrument internal disinfection machine, which can perform low-level disinfection of the internal structure of various medical instruments, and is effective against common pathogenic bacteria. Effective in killing, convenient and simple in disinfection. But the disinfecting effect of this invention is limited, poor to bacterial spore effect.

Contents of the invention

The purpose of the present invention is to overcome the deficiency of the prior art that the sterilization effect on bacteria is limited, and to provide a multi-purpose medical instrument internal structure sterilizer.

Technical scheme of the present invention is summarized as follows:

A multi-purpose medical instrument internal structure disinfection machine, including a box body, the box is provided with an ozone generator connected to a positive pressure air pump, a negative pressure air pump and a control circuit, the ozone generator is connected to a first conduit, and the The negative pressure air pump is connected to the filter through the second conduit, the box is provided with an atomizer, and the atomizer is connected to the first conduit through the third conduit, and the control circuit controls the positive pressure air pump, ozone On or off of the generator, atomizer and negative pressure air pump, the atomizer is provided with an aqueous hydrogen peroxide solution with a volume percentage concentration of 8% to 12%, and the concentration of the aqueous hydrogen peroxide solution is preferably 10%.

The filter can be selected from various types of filters, and the following filter can also be selected. The filter includes a cylinder, and the inner side of the cylinder is provided with an upper support orifice and a lower support orifice. A first non-woven fiber layer, an activated carbon layer and a second non-woven fiber layer are sequentially arranged between the lower supporting orifice plates.

The control circuit includes a 89C2051 single-chip microcomputer, and the 89C2051 single-chip microcomputer is connected to a current power supply through a wire through a filter, and the 89C2051 single-chip microcomputer is respectively connected to a positive pressure air pump, an ozone generator, a negative pressure air pump and an atomizer.

The present invention can be widely used in medical equipment, public pollution equipment, laboratory equipment, and monitoring instruments, especially for disinfection inside various medical instruments with pipelines, such as ventilators, anesthesia machines, pulmonary function testers, in vitro Disinfection of circulation machines and artificial kidney dialysis machines, which can sterilize the contaminated interior of the instrument without being corroded or damaged.

In practical application, it has the following advantages: it can avoid the cross-infection of the next user due to the contamination of the instrument after use; it can avoid the untimely disinfection of the instrument after use, and the breeding and reproduction of viruses, bacteria, especially bacillus inside the instrument; It avoids the time-consuming and laborious and extremely inconvenient disadvantages of medical staff disassembling and cleaning the ventilator and anesthesia machine for patients; avoids the short-term unusability of the instrument caused by the use of liquid disinfection that cannot be rinsed in time; avoids the use of liquid after disinfection The residue of the disinfectant causes allergic and toxic reactions to the patient; the negative impact of incomplete disinfection due to different disinfection methods is avoided, and the present invention has a strong bactericidal effect due to the synergistic effect of the two disinfectants.

Because the present invention is simple in operation, convenient in connection and intelligent in machine operation, problems caused by improper operation and use are avoided. After being sterilized by the invention, the gas discharged into the atmosphere can meet the national discharge standard.

Detailed ways

Below in conjunction with accompanying drawing, the present invention will be further described:

A multi-purpose medical instrument internal structure disinfection machine, comprising a box body 1, an ozone generator 2 connected with a positive pressure air pump 6 is arranged in the box body, (the ozone generator with a positive pressure air pump can also be selected such as the model is FQ -100 produced by Yueqing Baiyuekang Electronics Co., Ltd., which itself has a positive pressure air pump), negative pressure air pump 3 (the model of the air pump is QC02 produced by Yueqing Baiyuekang Electronics Co., Ltd.) and control circuit 4, the ozone generator and the first A conduit 5 is connected, the negative pressure air pump is connected to the filter 8 through the second conduit 7, an atomizer 9 is arranged in the box, and the atomizer is connected to the first conduit through the third conduit 10, and the control circuit controls the positive pressure air pump, ozone The generator, atomizer and negative pressure air pump are turned on or off. The atomizer is equipped with aqueous hydrogen peroxide solution. %, preferably 10%. Various types of atomizers can be selected for the atomizer, for example, the ultrasonic atomizer (CQ-WH2001B) produced by Tianjin Chuanqian Electronics Co., Ltd. is selected.

The filter can be selected from various types of various types, and the following structure can also be selected. The filter includes a cylinder 11, and the inner side of the cylinder is provided with an upper support orifice 12 and a lower support orifice 13. The upper support orifice and the A first non-woven fiber layer 14 , an activated carbon layer 15 and a second non-woven fiber layer 16 are sequentially arranged between the lower supporting orifice plates.
